Foot, mechanically, is the second most complex global structure of the human body, behind the hand. You can present different morphologies (shapes of the foot) and mechanical patterns (ways of move). This is due to two reasons: the role played in the past: since their employment was very similar to the hand, although never as accurate. With it, our ancestors could grasp objects, have better grip when climbing, the role played today: as one of the links in the chain that keeps you in balance and nuance that gives you at the time of your transport (walking, running, jumping,). Therefore, consists of numerous structures (bone, muscle, joint, nerve,), concentrated in a really small space compared with the rest of the body.
Let’s see what are: System osteoarticular foot consists of 26 bones. We can divide it into 3 parts: Tarsus: with 7 bones, which serve as base of support to tibia and fibula, and damping point by walking and running. Metatarsus: with 5 bones forming the foot bridge and offering stability. Phalanges: with 14 bones (3 per finger except the thumb, which has 2). It is not necessary for you to learn the name of each of the bones. What is important are the details.
Why do you think you will have so many bones? You think that by every union of two bones form a joint, having more than 30 foot. For what so many joints? This already invites us to think, for a future (when we see their functions and how to care for it), that the foot is a particularly mobile structure. Therefore, once again, we need move it! Muscular system here will not name each of the muscles that articulate the foot. I show you a drawing where are almost all from the back (there are also in the plant). Just say a couple of things: so many bones and joints imply the existence of still more muscles.
